Hello,
Quick question. If there is Medium Density Fibreboard, MDF, why not look to use high density fibreboard? I assume it would be even more solid and rigid when compared to MDF. I tried searching for sources online but couldn't find much. What does everyone else think? Matt

I didn't even know there was a high density fiberboard.

I know there's ultralite MDF which is fun stuff, but I just stick to the good ole A-grade MDF.

This weekend my friend and I worked on turning 8 sheets of MDF. (some laminated) and turning them into 15 loudspeakers.

I love the smell of Pine and Glue. :)

The MOE of a good grade of MDF is about the same as HDF. The biggest difference is weight....and cost. MDF is readily available while HDF is usually a special order. So basically, not worth the extra effort.

Pete is correct. HDF is very difficult to find and usually involves a special order for more than a DIY-er could use or store - my local experience anyway.
Looks like Chris is serious about this DIY stuff - 15 speakers in one weekend?

Not to mention it's murder on tools/blades. You'd swear the stuff was concrete it's so dense.

None of the speakers I'm building are gonna be for me. (Except for maybe some Diluceos which I'm tempted to make as I have an extra sheet of maple)

We couldn't do 15 speakers in one weekend, we just made the cuts and rips, and I started using a hole saw and router to make the driver cutouts. It may take us another weekend to finish assembly, and another to solder crossovers, install drivers, and sand/finish them.

We're only charging $30 an hour and work very fast when doing them in bulk which means ppl are getting them for a steal. You see the industrial equipment we get to work with? :D

One of my friends works with MDF and HDF at his business. He told me that the HDF just has much more of the glue/resins that hold it together. It definitely has a stronger smell. If you use it, I'd make sure that you use something to seal it or you'll be smelling the chemicals in it for a while.
